Stewart's lawyer, Shiel Edlin, told TMZ that the former Pittsburgh Steelers star is "very disappointed" that the marriage fell apart because he wanted to be "married for life."
However, he does expect that Williams will stop "vilifying" his client every change she gets.
"For reasons we cannot understand, [Porsha] displayed a reckless abandonment of anything close to the truth over the last eight months," Edlin said.
Edlin's comments come after Williams alluded that Kordell was gay in the season premiere episode of Real Housewives of Atlanta in early November.
"There were definitely times in the marriage that Kordell didn’t necessarily want me, physically, and that made me wonder, what does he want?” she said in the episode.
Stewart asked Williams for a divorce via Twitter before the end of last season's RHWA.
